Proportional Directional Valve 4WRZE25E325-7X/6EG24N9ETK31/A1M - Bosch Rexroth R901017352

The 4WRZE25E325-7X/6EG24N9ETK31/A1M routes pilot oil internally in both directions and works without a built-in pressure reducing valve. A size 25 axis therefore runs on 325 l/min nominal flow, guided by a ±10 V command value.

Benefits

• Internal pilot oil supply and internal pilot oil return keep the piping down to the four main ports.
• 325 l/min nominal flow with flow up to 870 l/min at a maximum operating pressure of 350 bar.
• Concealed auxiliary actuation lets the axis be moved while the electronics are switched off.
• Analog control with ±10 V command value at the on-board electronics, 24 VDC supply through a connector, 7-pole (6 + PE) according to EN 175201-804.
• UKCA conformity for electromagnetic compatibility to SI2016/1091, NBR seals for HL hydraulic fluid.

Technical data

Applications

The ISO 4401-08-08-0-05 hole pattern fits common size 25 manifolds on machine tools, presses and power units with axes in the medium power range. Three switching positions with spool symbol E set direction and flow rate in one step. During commissioning and service the concealed auxiliary actuation shifts the spool without an electrical signal.
